Hi

I have a facility which uses css and ajax to perform live plotting of  
routes between two London underground stations. The css plots are  
overlayed over a London Underground map, with each station as a hotspot.  
The underlying platform is Ruby on Rails.

I have incorporated certain Web 2.0 features like votes for the best  
routes, station name autocomplete, context sensitive points of interest  
along the selected routes etc.

The URL is [http://public.ok2life.com/tube/routes](http://public.ok2life.com/tube/routes). As usual, let me know  
if you have any feedback by either using the provided MessageBoard, or  
send me an email.

David

[Ajaxian.com](http://Ajaxian.com) has got some cool suggestions 🙂

My favourite is Pragmatic Ajax, but I am afraid you will have to choose  
your own favourite title. I have not seen a book that covers every trick  
for something as complex as Ajax yet.
